Brand: Festo

Quarter turn actuator DFPD-120-RP-90-RD-F0507-R3-EP

The Festo 8048128 is a double-acting industrial valve actuator featuring a gear rack and pinion structural design with a 120 actuator size and a 90-degree swivel angle. It operates within an operating pressure range of 2 bar to 8 bar (29 psi to 116 psi) at a nominal operating pressure of 5.5 bar, and includes an end-position adjusting range of -5 to 5 degrees at both 0 degrees and the nominal swivel angle. Certified for safety functions to ISO 13849 and IEC 61508, the unit supports up to SIL 2 in low demand mode, SIL 1 in high demand mode, and SIL 3 in a redundant architecture.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.

Devices type according to VDMA 66413: Safety device
Safety function: The safety function consists of the actuator switching to the dened | safety switching position. This switching movement is achieved by | pressurizing the corresponding pressure chamber with compressed air. | The value of the torque generated depends on the pressure diﬀerence | between the two pressure chambers separated by the piston.
Safety integrity level (SIL): Up to SIL 2 low demand mode | up to SIL 3 in a redundant architecture | up to SIL 1 high demand mode
Certied for safety function to ISO 13849 and IEC 61508 (SIL): Product can be used in safety-related parts of control systems up to SIL | 2, low demand | Product can be used in safety-related parts of control systems up to SIL | 1, high demand | up to SIL 3 in a redundant architecture

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
